rsync 常用参数:

-a, --archive 归档模式,等于-rlptgoD
-r, --recursive 递归模式;
-l, --links 保持符号连接;
-p, --perms 保持文件原有权限;
-t, --times 保持文件原有修改时间;
-g, --group 保持文件原有用户组;
-o, --owner 保持文件原有属主;
-D -devices -specials,保持块设备文件和特殊文件;
-I 强制扫描,放弃“quick check”策略(quick check策略,通过查看文件的时间戳和文件大小,先排除一批认为相同的文件[rsync不会对文件夹本身做“quick check”]);
-z, --compress 压缩,默认的压缩算法和gzip一样;
-v, --verbose 详细模式输出,传输是的进度信息;
-q, --quiet 精简输出模式;
-R, --relative 保持全路径;
-P, --progress  显示传输进度(百分百)
--delete 本地删除某一文件,远程也同步的删除该文件,保持严格的一致(不加该参数,则表示只增不减);
--exclude="*.tmp" 排除某些文件;
--exclude-from=FILE 排除FILE中指定模式的文件;
--port=PORT 指定其他的rsync服务端口;
rsync 是一个文件传输程序,能够通过快速微分算法高效的进行远程更新内容。

用法: rsync [OPTION]... SRC [SRC]... DEST
  或  rsync [OPTION]... SRC [SRC]... [USER@]HOST:DEST
  或  rsync [OPTION]... SRC [SRC]... [USER@]HOST::DEST
  或  rsync [OPTION]... SRC [SRC]... rsync://[USER@]HOST[:PORT]/DEST
  或  rsync [OPTION]... [USER@]HOST:SRC [DEST]
  或  rsync [OPTION]... [USER@]HOST::SRC [DEST]
  或  rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST]
':' 用法是通过远程shell连接。
而'::'和'rsync://'用法是连接到rsync守护程序,并且要求 SRC 或 DEST 以模块名称开头。
